I think a workable rule is that you need a verb with at least two syllables, not that you have to use the verb twice. So it is ok to say 你把门打开来 你把工具整理一下 你把垃圾拿去丢掉 But it is not ok to say 你把门开 你把垃圾丢 你把电话放 You can make all the "not OK" examples OK by adding another syllable to the verbs: 你把门打开 你把垃圾丢掉 你把电话放着

“把门开开”and“把门打开”it meaning is the same, but“把门打开”～Open the door.“把门开开”～Could you open the door?The last sentence sounds morecloser.It often used between friends.

my dear friend, thanks a lot!:)
